I'm assuming you are doing an ssh to the remote Sun box and then 
running emacs, rather than accessing remote iles using something like
tramp or ange-ftp.

Check to see what TERM setting the remote emacs believes it is running
under. I suspect the most likely cause is that the remote emacs
doesn't realise it is running under a terminal which can support
colour. If this is the case, you will have to see if there is a
suitable colour capable termcap/terminfo setting which is compatible
with the tty. I have seen this problem when users are running on Linux
and connect to a commercial Unix system like solaris or Tru64, which
doesn't have termcap/terminfo entries for terminals of type Linux or
Console (as used in Linux). 

If you can find a suitable termcap/terminfo entry on the solaris box,
you may need to set your TERM variable explicitly when you login to
force it to use that entry.

Alternatively, use tramp from a local instance of emacs - you will get
colour syntax highlighting and probably better responsiveness
(assuming thats why your running under a console rather than X).
